Mobile concrete mixing plants are typically sized to fit on a roadable trailer, or are made up of assembled components that can be disassembled from one another and individually transported by road, such as on a semi-trailer. Typically, mobile concrete mixing plants are temporarily set up in a location near an immediate need for wet concrete, such as alongside a new road or a building project. The mobile mixing plant is supplied with concrete ingredients, such as cement, sand, aggregate, and water, which are mixed together in desired proportions and dispensed as flowable concrete.
